LOCK FOB SLIDING DOORS.

Specification o Letters Patent.

Patented June ,29, 1909.

Appcaton filed March 10, 1909. Serial No. 482,446.

To all who/m it 'may concern:

Be it known that l, Janus n.. BnNnnire'r, a citizen of the UnitedStates, and a resident ol" the city oi New York, borough ot' Manhattan,in the cour and State ot New York, have invented a new and improved Lockfor Sliding Doors, of which the following is a lull, clear, and exactdescription.

My invention relates to locks ter sliding doors, my more particularpurpose being to produce a lock requiring no key and easily manipulatedby hand for the purpose ot sccuring the door.

More particularly stated, my invention comprehends a plate mounted upona movable door and sunken thereinto, Ythe plate being provided with arecess of a general annular term, and a hinge member mounted upon somestationary part adjacent to the doorway and provided with a pivotallymounted bolt tor engaging the plate by entering the recess thereof, thearrangement ot the parts being such that the swinging plate may be swungback into a normal position of inactivity or may be temporarily securedrelatively to the plate in the movable door member.

Reference is to be had to the accompanying drawings forming a part otlthis spcci'lication, in which similar characters of reference indicatecorresponding partsin all the Vfigures.

Figure 1 is a sectional perspective showing my improved lock in use upona sliding door, Fig. 2 is a substantially central horizontal sectionthrough the parts shown in Fig. l Fig. 3 is a horizontal section similarto Fig. 2, but showing the door as moved back and the swinging bolt asoccupying its normal position ot' inactivity; Fig. l is a front view ofthe metallic plate which is carried by the movable door member Fig. 5 isan edge view ot the same; and Fig. 6 is aplan view ot' the hinge membercomplete.

Boards 7, S are so arranged and supported as to form a door pockettherebetween, and movably mounted within this door-pocket is a doormember Q. Carried by the door member 9 and sunken into the same is ametallic plate 10 provided with a recess 11 having the general form of awedge, and being bounded by a shoulder 12, as will be understood fromFig. t. The edge of the plate 10 opposite the shoulder 12 registersflush with the adjacent surface of the door member t),

as may be seen at 13, Fig. o.

A latch 14 is, by aid ot a pivot 15, mounted upon the plate l() and maybc turned by hand. rlho plate 1() secured upon the door member 9 by aidol' screws 16. Mounted upon a stationary post 17 is a plate 1S, thisplato being secured to the post by aid ot screws 1.9. Journalcd upon theplate 18 is a swinging plate 21 which is provided with a knob 22, thisknob being ole proper size to easily enter a hole 20 in the plate .18.

rlVhe operation of my device is as follows: When it is desired that thedoor member 9 may be moved freely in either direction, the swingingplate 21 is turned into the position indicated in Fig. 3, the knob 22entering the hole 20. 'lhe swinging plate 2]. is now completely out otthe way so as not to interfere with the tree .movements ot the doormember. It', however, it be desired to secure the door 9, the door ismoved into suitable position, as indicated in Fig. 2, and the swingingplate 21 is moved angularly outward so that the end ol the plate engagesthe shoulder 12. Any movement oi the sliding door Q toward the right,causes the swinging plate 21 to act like a pawl that is to say, to biteagainst the shoulder 12 and ellectively prevent any travel ot the doormember toward the right. The operator next turns the .latch 14 into suchposition that it hangs downwardly from the pivot .15, as indicated inFig. 1. The swinging plate 21 can not now be moved away from the plate10 until the operator again turns the latch 141; into its normalposition which is indicated in Figs. i and 5.

Having thus described my invention, l claim as new and desire to secureby Letters Patent:

1. A device of the character' described, comprising a door membermovable in thc general direction ol its width, a plate mounted upon saiddoor member and provided with a recess having the general lorm ot awedge and provided with a shoulder, and a plate journaled upon astationary member disposed adjaccnt to the path ot travel ot said doormember and adapted to swing, said plate being provided with a portionfor entering said recess and engaging said shoulder.

2. A device of the character described, comprising a movable doormember, a metallic member sunken thereinto and provided with a shoulder,a stationary member disposed adjacent to said movable door member, aplate secured to said stationary Cil Cir

lOl)

member7 and another plete pivoted upon said last-mentioned plate andadapted to engage seid shoulder of said metallic mem- 3. The combinationof a movable member adapted to travel in a door pocket, e ste.- tionarymember disposed adjacent to said door pocket, a plete mounted upon seidstationery member and provided with en opening, e swinging pletepivotallv mounted upon seid inst-mentioned plete and provided with e,knob for entering said opening when seid swinging ple-te is turned forthis purpose, and e Closure member disposed partially Within said doorpocket and adapted to travel Within the seme7 seid door pocket beingpro-.

vided Witli a portion having a shoulder for engaging the outer end ofsaid swinging plate.

Ll. The combination of a movable door, a

i stationery member disposed adjacent to seid. door, a plete pivotallymounted upon said stationary member and adapted to be swung toward andfrom said door, and a latch mounted upon said door and adapted to engageseid plete for the purpose of holding the same in engagement With seiddoor.

ln testimony whereof l have signed my neme to this speoiiioution in tliepresence ol two subscribing Witnesses.
